Subject: [PATCH] Enhanced user ignore feature

* Regular content by ignored users is now converted into grayscale with
a non-hover opacity of .5
* Messages are collapsed to a single notice, but will reveal the full
message on click
* Blocking a follower will now remove the follower-state and block
future attempts to follow again while still being blocked
